Synthesizing training data for broad area geospatial object detection

1. A system for broad area geospatial object detection using synthetically-generated training images for improved training of a deep learning model comprising a computing device comprising a processor, a memory, and a plurality of programming instructions stored in the memory and operable on the processor, wherein the plurality of programming instructions:

(a) retrieves a digital model of an object of interest from a data store;

(b) creates a flattened image from the retrieved digital model;

(c) compares the flattened image to a real geospatial image comprising an instance of the object of interest and associated background;

(d) scales the flattened image to align with the real geospatial image of the instance of the object of interest and separates the flattened image from the background of the real image;

(e) applies a plurality of environmental effects to replicate seasonal, time of day, associated brightness, and environmental factors consistent with a geographic location of the real background image to create a plurality of modified synthetic images;

(f) creates a plurality of shadowed, modified flattened images for the object of interest as if it were physically located and oriented where it would be affected by real-time and real-world shadowing;

(g) adjusts the shadowed, modified flattened images to resemble the real image;

(h) identifies and demarcates a footprint associated with each of the shadowed, modified flattened images;

(i) overlays the demarcated footprint onto a real image;

(j) generates a labeled corpus of manipulated synthetic training data comprising at least a portion of the modified flattened images; and

(k) trains a deep learning model comprising a convolutional neural network to recognize objects of the same type as the object of interest in geospatial images.

2. The system of claim 1 , further comprising an image analysis server comprising a second processor, a second memory, and a second plurality of programming instructions stored in the second memory and operable on the second processor, wherein the second plurality of programming instructions:

(a) uses the deep learning model to automatically identify and label all objects of interest in a received data set comprising a plurality of unanalyzed orthorectified geospatial imagery; and

(b) outputs the locations of the identified objects of interest.

3. A method for identifying objects of interest in geospatial images using a deep learning model and synthetically-generated training images the method comprising the steps of:

(a) automatically generating, using an image manipulation computer, a flattened image of an object of interest from a digital model of the object of interest;

(b) manipulating the flattened image to create a plurality of synthetic images comprising at least one of the object of interest, placing the object of interest in the plurality of synthetic images in a plurality of locations, environments, orientations, scales, exposures, and foci in order to create a large corpus of synthetically-generated training images;

(c) training, using the large corpus of synthetically-generated training images, a deep learning model comprising a convolutional neural network to recognize objects of the same type as the object of interest in a plurality of unlabeled geospatial images;

(d) analyzing the plurality of unlabeled geospatial images using the deep learning model to identify objects of interest; and

(e) generating an output file comprising location, classification, and quantity of the object of interest in each of the plurality of geospatial images.
